The question doesn't make sense. Watts are the product of volts and amps so you could have 1 V with a current of 1 amp = 1 watt or 10V and a current of 0.1 amps = 1 watt or 100V and a current of 0.01 amps = 1 watt etc.

∙ 12y agoIn order to figure watts (or power), you have to have 2 values to go off from. Using Ohms law, you would multiply amperage times volts to get watts.
For instance a 12 volt circuit drawing 2 amps would consume 24 watts of power (12*2=24).
A 60 watt light bulb powered by 120 volts in a house would draw .5 amp of current (60/120= .5).
A device in the house drawing 2 amps of current would consume 120 watts of power (2*120 = 240).
A 1500 watt toaster in the house would draw about 12.5 amps. (1500/120 = 12.5 amps). So a toaster in a house should be on a separate circuit that is fused for 15 amps.
For further information punch in "Ohms law" in a search engine.

4 ohms equals how many watts?
Ohms does not equal watts. You need to know what voltage is across the resistor to determine how many watts it is drawing or how many watts the resistor should be rated for.Power is the voltage across the resistor SQUARED divided by the resistance. If this 4 ohm resistor has 12 volts across it then the watts power is (12 x 12) / 4 = 36 watts.1 Watt equals 1 Volt times 1 Amp.
How many amps are in 40 watts?
That depends on circuit voltage. 1 watt is equal to 1 volt times 1 amp.
How many watts are in 100 2.5 volt bulbs?
This question does is not answerable. A watt is a volt times an amp. With out knowing how many amps the bulbs use there is no answer.
How amps needed to supply 1950 watts?
That depends on circuit voltage. 1 watt is equal to 1 volt times 1 amp.
500 watts is how many amps?
The same number as 250 oranges is apples. A watt is a volt times an ampere.
How many watts is 1 v?
One volt is zero watts.
How many watts in 1 ampere 230 volt?

How many watts does a 36 volt battery charger use?
Not sure about how many Watts your 36 volt charger uses, but you can find out by this formula... Volts X Amps = Watts.
How many watts does my 12 volt 2 amp battery charger draw?
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
How many watts does a 3 amps use in America?
On a 120 volt supply, up to 360 watts. On a 240 volt supply, up to 720 watts.
How many watts need for seven ampere's and 120 volt's?
770 watts.
How many amperes in a watt and how many watts in a volt?
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
How many watts does a 1000 watt 480 volt sports light draw?
Your question answers itself... 1000 watts, when operated on a 480-volt source..
How many amps is 400 watt in 240 volt?
calculation for Watts is = volts X amps P=IE P= Power(WATTS) I = Current(AMPS) and E = Voltage(VOLTS). So: I = P/E and E = P/I therefore: 1 watt = 1 ampere x 1 volt If you havea 240 volt lamp that is drawing .5 amp then it is using 120 Watts
